Radiator selection help

[Mictlan]

I want rig my new mobo (an Iwill DVD266u-RN, must be in my home by the end of November) with a watercooling setup. AS this will be cooling a dual PIII processor, I suppose I'll be needing a big radiator. I was thinking in going to the junkyard to get one, but I'm a little bit lost in what to ask for (as my current knoledge in auto parts compete with my Linux expertise). So, if someone could be so gentle to tell me which brand of car cooler I must search? If you can tell me to which car it's normally attached will also be helpful.

What you would be looking for is either a transmission cooler or a heater core. It depends on what size you want, there is no "best". I recommend you get one that is made with the same metal as your water block. What I have is the transmission cooler for a Chevy truck. The reasons I picked that is because it is big, flat and has copper tubes. Some of the other ones I looked at was the heater core for a Grand Am (brass) and the radiator for a Honda motorcycle(copper and brass). Pick what size you want and look around. Good hunting!
